Description
The Sinkits Super Short undermount sink clamp is a patented clamping system for mounting sinks to granite, quartz, concrete, or any other stone or hard surface material without adhesive. The Super Short version is built for cabinets and openings with limited clearance beneath the counter.
How the Sinkits Undermount Sink Clamp Works
Instead of relying on epoxy cure time or a mess of clips, screws, washers, and anchors, this undermount sink clamp installs with a 3/4 inch anchor bolt. A fabricator drills a hole and inserts the clamp, and the sink is mounted without waiting for adhesive to set. That single step replaces the multi-part clip hardware traditionally used for undermount installs, which cuts both install time on site and the number of small parts a crew has to keep stocked on the truck.
Undermount Sink Clamp Specifications
| Version | Super Short |
| Anchor bolt | 3/4 inch |
| Compatible sink rim thickness | Up to 3/8 inch |
| Compatible surfaces | Granite, quartz, concrete, and other stone or hard surface material |
The Super Short clamp is designed for sink rims up to 3/8 inch, making it a strong fit for many stainless-steel undermount sink installations. Because the Super Short version has a shorter overall profile than the standard Sinkits clamp, it fits jobs where drawer boxes, plumbing, or a shallow cabinet base leave less room to work from below.
